One well-known insecticide is Bacillus thuringiensis (a bacterial disease infects lepidoptera, diptera and coleoptera) which has a significant impact on other organisms and is deemed to be more environmentally friendly than synthetic pesticides. The toxin extracted from bacillus thuringiensis has been incorporated directly into plants through the use of genetic engineering.
Biocides are used instead of chemical insecticides with significant damage. This technique appeared in which certain organisms are used such as bacteria as a mean to combat pests that attack crops. Biocide term is used for the biological microbial pest control agents that have been applied in a manner similar to chemical pesticides. These are usually bacteria, but there are other control factors such as fungi, viruses and nematodes. Weeds and rodents have also been controlled by microbial control, and BT cotton is the best example used in India (Farhan, 2011, AEBM).
